THE RISK

Critical Risk

Why create_batch_payment needs a policy

This tool initiates financial transfers (B2P = Business-to-Person payments) to PicPay users in bulk. Misuse could result in unauthorized mass fund disbursements. Financial is the highest severity category, and batch execution amplifies the blast radius to critical.

From the tool's definition 'Submit a batch of B2P transfers in a single request' and 'independent transfer to a PicPay user' — this tool moves money to multiple recipients in one call

POLICY

How to control create_batch_payment

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for create_batch_payment:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_batch_payment": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create_batch_payment is blocked until a human approves it. The rest of the server keeps working.
